John Steed does not have a wristwatch with a laser beam or a circular saw, nor does he have a jetpack and usually John Steed is an agent who does not need such gimmicks, but some of his brollies have a few great functional additions. Under normal circumstances, Steed does not need these anyway, but from time to time he has to use the equipment. Such technical devices seem to be very popular amongst spies as similar ones were used by agents in The Charmers.

1. The camera
Sometimes Steed has to secretly photograph, which is especially difficult when someone is in the same room. In such a case, he uses his brolly camera. Steed used conventional miniature cameras to photograph classified material.
2. Recording device
The handle of this special brolly of Steed hides a recording device, to leave a message for himself or one of his partners. Steed can record, play forwards and backward using two buttons, a red one, and a green one, it also has a mono speaker.
Used one time during the Avengers in A Funny Thing Happened on the Way to the Station.
3. The gas trigger
Steed can press a button at the handle of the brolly which releases sleeping gas from the tip of the brolly.
Used one time in Escape in Time
Steed's brolly shrinked once in Mission Highly... Improbable!
